“Rapid review methods need to be chosen to fit the needs of the review, each of which may have different challenges. Collaboration between those producing rapid reviews and commissioners is crucial when choosing methods to ensure that the needs of commissioners are met and limitations associated with the chosen methods are understood.”

“From the three reviews examined, limiting the search to fewer databases had no or minimal impact on the review conclusions despite the variable number of studies that would be missed and records needed to sift. More exploration during the scoping search prior to commencing the review will aid the decision on whether to limit the search to fewer databases.”

I like it as it backs up my position (?confirmation bias) that searching lots of databases could well be construed as an unethical pursuit. Resources are limited and therefore extending costs to cover extra databases needs to be clearly justified otherwise it’s wasteful; which is the unethical bit!
